 In #63430 isset() ternary were replaced with null coalescing.

 We also should replace if isset() return with null coalescing.

 {{{#!php
 <?php
 -        if (isset($this->items[$key])) {
 -            return $this->items[$key];
 -        }
 -
 -        return 'fallback value';
 +        return $this->items[$key] ?? 'fallback value';
 }}}
